31. Dependence Characteristics of Face Recognition Algorithms
Andrew L Rukhin, Patrick J Grother, P Jonathon Phillips, Stefan D Leigh, E M Newton, Nathanael A Heckert
Nonparametric statistics for quantifying dependence between the output rankings of face recognition algorithms are described. Analysis of the archived results of a large face recognition study shows that even the better algorithms exhibit significan ...
32. Transformation, Ranking, and Clustering for Face Recognition Algorithm Performance
Stefan D Leigh, Nathanael A Heckert, Andrew L Rukhin, P Jonathon Phillips, Patrick J Grother, E M Newton, M Moody, K Kniskern, S Heath
The performance of face recognition algorithms is recently of increased interest, although to date empirical analyses of algorithms have been limited to rank-based scores such a cumulative match score and receiver operating characteristic. This pape ...
33. A Statistical Test Suite for Random and Pseudorandom Number Generators for Cryptographic Applications
Special Publication (NIST SP)
Andrew L Rukhin, Juan Soto, James R Nechvatal, Miles E. Smid, Elaine B Barker, Stefan D Leigh, M Levenson, M Vangel, D L. Banks, Nathanael A Heckert, James F Dray Jr, S C. Vo
[Superseded by SP 800-22 Revision 1a (April 2010): http://www.nist.gov/manuscript-publication-search.cfm?pub_id=906762] This paper discusses some aspects of selecting and testing random and pseudorandom number generators. The outputs of such generat ...
34. Statistical Analysis of Partial Discharge Phenomena - Time of Occurrence Distributions
X. Han, Nathanael A Heckert, James J Filliben, Yicheng Wang
This paper presents time-of-occurrence (phase) distributions of individual pulsating partial discharges (PDs) which occur in a point-dielectric gap in air for ac voltage conditions. It is determined that the pulse phase distribution is adequately mo ...
